2 SHEETS-SHEET 2 p the 'oint where the sockets are to be formed in tie tie .is a yoke B. In fact'there are two yokes arranged upon the mold, one at either end thereof, to provide sockets for receivin' the fastenings for the two rails. Description will,- however, only be made of one. The yoke B, as said before, rests upon the top ed es of the mold and is made sufliciently'wi e to rest thereon with a relatively wide bearin It is attached tothe mold by means 0 thumb screws 12 which fasten through the lugs 6 dependent from the yoke on either side of the mold, the fastenings being threaded in and extending through these lugs and bearing against butts 1) dependent from the outwardly flaring" edge of the angular reinforcement a extenda ing along the top edges of the sides of the mold, as before described. It is to be observed, also, that the butts b are inwardly inclined so that as'the thumb screws 1) are ,tightened against them the tendencywill be for the screws to slide along the inclined surface of the butts and, accordingly to draw the yoke tightly against the top of the mold ftliereby holding it securel in place. A release of the yoke may be 0 tained simply by releasin the thumb screws.

' Attac ied to the head of the yoke B are brackets Z). There are two of these brackets separately arranged onthe head of each yoke and they extend laterally from it in opposite directions; Each of the brackets comprises an arm I) which adjustably connects with the head of the yoke as will here inafter be explained and a clamping portion I) for receivin and holdin a rod 6. These rods carrysoc ets C which are the sockets to be molded into the tie for receiving the rail fastenings, the rods 1) being arranged to extend down into the cavity of the mold and rigidly hold the sockets therein during the placing of the plastic material or cement in t e mold and during its setting or hardening.

The sockets must, of course, be very accurately located. In their vertical disposition the sockets should be so held that the open mouth of each socket will be flush with the top surface of the tie when formed. The lateral pdsitioning of the sockets should also be such that the sockets will lie at points just adjacent to the flanges of the respective rails in order the rail fastenings may enter the sockets and properly engage with the flanges of the rails. The vertical positioning of the sockets is arrangedfor by adjustably securing the rods to the brackets. In Fig. 7 the portion bf of the brackets into which the rods fit is made vertically grooved or channeled with an arm 7) extending from the vertical grooved portion of the bracket,

Jbcing held}-t-herein by a .thumb screw b which passes through'.the arm b of the bracket and bears against the side of the rod binding it to the bracket. Upon loosening the thu'mb screw avertical adjustment of the rod may be obtained and consequently a vertical positioning of the socket carried by the rod. Other means for adjustably re- 'ta'inin the rodsmay be employed, as for example, in Figs. 8 and 9 the bracket to which the socket-bearing rod is secured-comprises a slotted arm 6? the same-as shown in Fig. 6, which adjustably conn cts with" the head of the yoke. The outer end portion of this am, or in other words, that portion thereof in which the rod fits comprises a-slit head 6 having in it an opening for vertically receiving the rod .and in which the rod may be moved adjustably, the head being tightened around the rod for maintaining it at any point of adjusted'position by means of a screw b passing through ears I)" extending from therespective sidesjof the split head.

In Figs. 10 and 11 I have shown chucks I b, 6 arranged upon" the ends of the slotted arms 6- for receiving and holding the socketbearing rodsbh With respect now to the means for' obtaining an adjustable lateral positioning of the rods and-sockets. "Each of the slotted arms 'b, on the end of which the socket-bearin rods are'borne, connects, as said before, with the heads of the respective'yokes, the arms being attached to the yokes by means of bolts 1) which pass "through the slots inthear'ms'and through also nuts or bearings'b on which the arms rest and then fasten into the headsof the vokes. Thus retained, when any one of the bolts b is loosened the arm 6 retained by 4- it may be moved longitudinally or turned laterally around the shank oftlie bolt whereupon the socket-bearing arm and socket carried by it may be moved to any desired position of lateral adjustment and maintained in such position upon again tightening the bolt. I prefer that the nut or bearin bf upon which the arm rests may turn wit the arm as it is turned around the shank of the bolt. Accordin 'ly there extend upwardly from the nut or caring I)? flanges ,b". which embrace the arm on either side thereof. I

prefer also that a washer'b may be inter posed between the head of the bolt and the top surface of the arm. In order that this washer may not turn on thebolt inde' end cntly of the arm it is made square and arranged between ribs b extending from the top surface of the arm at points just adjacent to opposite side edges of the washer.

In Figs. 10 and 11 no washer is shown, the head of the bolt bearing directly against the top surface of the arm on either side of.

the slot formed in it, the head being wider than the slot-,ifi the arm. a
